Leviticus 13:47-52

⁴⁷And any clothing of wool or of linen in which is the mark of the disease;

⁴⁸If it is in the threads of the linen or of the wool, or in leather, or in anything made of skin;

⁴⁹If there are red or green marks on the clothing, or on the leather, or in the threads of the cloth, or in anything made of skin, it is the leper's disease: let the priest see it.

⁵⁰And after it has been seen by the priest, the thing which is so marked is to be shut up for seven days:

⁵¹And he is to see the mark on the seventh day; if the mark is increased in the clothing, or in the threads of the material, or in the leather, whatever the leather is used for, it is the disease biting into it: it is unclean.

⁵²And the clothing, or the wool or linen material, or anything of leather in which is the disease, is to be burned: for the disease is biting into it; let it be burned in the fire.
